MOLDING-MACHINE.

SPECIFICATION forming part of LettersPatent No. 249,246, dated November 8,1881.

Application filed Aprils, 1881. (No model.)

To all whom it may concern Be it knownthat I, GEORGE WJLANDON, of Baltimore city, State of Maryland, havein- I vented certain new and useful Improvements 5 in Molding-Machines; fandl hereby declare the same to be fully, clearly, and exactly described as follows, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation of the part of an- I ordinary molding-machine to which myinvention relates.

reciprocating the cutter vertically. Fig. 4 is a side elevation of the cutter, and Fig. 5 is a plan of the molding which the machine is designed to make. r

The object of my invention is to provide an attachment for molding-machines of the wellknown standard patterns, whereby varieties of moldings can be made which haveheretofore only been produced by the tedious and expensive method of carving by hand;

The principal form of fancy molding in general use is what is termed shell-molding. 2 5 The design is produced by forming in the outer head of the molding, at regular intervals, a series of concavities having parallel beads similar to those on the convex surface of a mussel-shell, and hence the term used to 0 designatethemolding. Theseconcavitieshave heretofore been made by hand-chiseling at a cost of about a half a cent per foot of molding. I produce them in the operation of cutting the molding itself by means of a simple 3 5 attachment to the machine.

In the drawings, A is the frame of the wellknown Lee molder, and B is the shaft, carrying a cutter-head, O, and cutter D. On the side of the machine are bolted lugs a, between which is pivoted a lever, 12, carrying at one end- Fig. 2 is a top plan of the same; i Fig. 3, a side elevation of the attachment for.

three bearings, h h h, which are susceptible of a lateral sliding motion, carrying the shaft B .50 and cutter-head to one side.

The shanks ot' the clamp-handles pass through slots in the bars, in which slots they slide freely with the lateral motion of the shaft 13.; A pulley, f, near the lower end of the shait, is driven by a belt, F, as shown. H I

In operation the cutters D are securedlbv bolts 61 at the proper angle in the cutter head wood is fed in, as usual, at the end. .Theojr i nary beads are formed on the molding befo' e'it en counters the cutters 1). It will be nndystmd that a horizontal reciprocating motion im-1 1 parted to the cutter-head (J byuiean i of th 65 shaft H, lever b, and cam race 0H,:iibf3lt1fiki1f whereby the cutters are caused to 'apvroach and recede from the molding, and forn in its edge a series of concavities, regulated as to depth and intervals, respectivelnxby tllG fhIOW of the lever and the relative speed a" the feed mechanism and the dislrE. Thosovjict'ors may obviously be readily adjustedpb flat the cut is determined in they particuiiars a A8 to the face design of the cut th l, Of Course, depends upon the contour of tlfi gfl f t cutters D. In making shell-rid g e e d of the blade is hollowed,f(s Fig. 4,) and toward the concavity run a sores of J grooves or channels, m, being. pitched g-tan' angle to the blade. The sections ofth e iear face ofthe latter made by these circular grooves are elliptical, r m

and hence the resulting rut formed bya revolution of ,the cutter hegd is circular in crosssection, elliptical in loigitudinal section, and 8 5 has elliptical beads. Y The efl'ect is that of the surface of a shell, tl'e molding N having the cuts an, as shown. In this case these cuts are horizontal. When it is desired to incline them Irnake useof the attachment shown in Fig. 3, the desi ll of which is to impart to the cutter 'head, in addition to the horizontal motion,;.a Vertical reciprocation.

on the shgit B is mounted a loose sleeve, k,

b g e f tars Ll, that are vertically adjusta- 5 (Land the machine being set in motionithe Clamp-handles c serve to secure the bearings when desiredfl as shown. To the sleeve 70 is attached a rod, K, adjustabl y connected by means of a pin and holes, j, to one end of a bell-crank lever, J, pivoted to the frame A. The other end of the lever is slotted and embraces a in h on acol- 5 a a termined by the positionpf the collar t on the S shaft H.

From the foregoing it will be seen that the shaftB, while turningatany desired speed, may have imparted to it a rise and fall anda lateral reciprocating motion, each independently ad- 2o justable, whence it follows that, suitable knives being used, an endless variety of cut may be made. Averypleasingdesign,whichisreadily producible, may be mentioned-namely, that of a series of inclined grooves running partly around the face of the outer head. The effect is that of a rope or cord wrapped around the bead.

Thedevice is attached to the molder at a \cost that is ofi'set by the first days work. \No end of beautiful designs can be made by nfeans of a few knives and cam-disks, EU

Tqitee knives and three disks, for instance, will mat; eighteen diflerentclesigns of molding, in-

vok the aid of the mechanism shown in Fig.

3, wiihout even alteringadjustments, and these latter-being infinite the variety is likewise.

WVha; I claim is-- 1. In combination with the disk E, having a cam-race on its periphery and mounted on the driving-shaft of the molder, the lever b, pivoted at the side of the machine, and connected with the cutter-shaft B by means of the rod H and sleeve G, as set forth.

2. In combination with the revolving shaft and cutter-head, the arm K, attached to the bent lever J, whose opposite end is connected with the mechanism for reciprocating the revolving shaft laterally,-as set forth.

3. In combination with the revolving shaft and cutter-head, the arm K, adjustably connected with the bent lever J, the opposite end of which engages with a collar adj ustably mounted on the shaft H, which latter effects the lateral movement of the cutter-head, as.

and for the purpose set forth.

4. In combination with the cam-disk E, leverb, and shaft H, connected with the cuttershaft B, as described, the bent lever J, connected with the shafts B and H, whereby the cutter-head is given a lateral and a vertical reciprocating movement, as set forth.

5. In combination with the revolving shaft and cutter-head, the arm K and lever J, having slot which embraces the pin h, adjustably secured to the shaft H, the lever 11, and camdisk E, whereby the vertical motion of the cutter-head is regulated both as to its extent and as to the period of its occurrence with reference to the lateralmotion of the same, as set forth.
